4 Claims. l

This invention relates to a loom, more particularly to the back binder for the shuttle box of the loom.

The back binder is usually pivotally mounted and resiliently pressed into the shuttle box at a location to be contacted by the shuttle when the shuttle enters the box. The resilient pressure is usually through the protection rod. The back binder is sometimes made in such a manner as to have inherent resiliency by means of a slot extending lengthwise thereof. Sometimes the back binder is covered with some resilient material. The exact position of its contacting surface is somewhat indeterminate.

One of the objects of this invention is to provide an arrangement for nicely adjusting the shuttle contacting surface of the back binder to provide maximum area of contact between shuttle and binder.

Another object of the invention is to provide for better checking of the shuttle with less binder pressure.

Another object of the invention is to reduce wear on both shuttle and back binder.

Another object of this invention is to provide a means for adjusting the position of a movable part of a back binder such for instance as a resilient tongue so that the surface of the back binder which contacts the shuttle may be varied as'to its position relative to all of the rest of the shuttle box.

More specifically an object of this invention is to provide a micrometer adjustment of this movable part of the back binder such for instance as by a threaded member or screw.

box and picker and picker stick;

Fig. 4 is a section on line 4-4 of Fig. 2;

Fig. 5 is a section on line 5-5 of Fig. 2.

In proceeding with this invention, I mount an abutment in the movable portion of the back binder and thread a member through the body portion of the back binder to engage this abutment so as to swing this movable portion to cause its surface which engages the shuttle to be forced into the path of the shuttle or removed from the shuttle path as occasion may require.

With reference to the drawings, Ii) designates generally the body of the back binder which is usually made oi wood but may be made of any light metal as desired. An opening I I is provided for pivotally mounting the back binder IU and is formed with a bushing l2 which is secured therein. This back binder thus may be mounted on the pivot pin I3 (shown in Fig. 3) to extend through the back wall lll of the shuttle box desthe pivot inwardly and longitudinally of the back` binder terminating in an opening 22 and provides a resilient movable longitudinally extending part 23 as a tongue extending along the inner portion of the binder adjacent to the swell I6 thereof. A cushioning surface `2li extends along this part 23 and also along the inner end portion of the back binder 25, which cushioning surface may be of leather as may be desired. The plate 26 is provided at this smaller end 25 to be pressed upon by the protection rod. Movement of the protection rod through this plate 26 serves to actuate this protection 'rod to lift the dagger when the shuttle is in position in the box.

In order to adjust this movable part or tongue 23 I have provided an abutment surface 21 (see Fig. 5) which is formed by inserting a threaded member 23 from the inner surface of the back binder and beneath the cushioning cover 24, such for instance as by means of a screw having a head 29 and slot 3i) therein. This will be held securely in position by reason of the threads engaging the surrounding walls of the opening through which it extends. In order to engage this abutment I have provided a set screw 3l which extends through a hole 32 in the body and has threaded engagement at with a plate 33 which is held on the outer surface of the back binder by means of screws tl. This threaded opening 35 threadingly receives set screw 3l which may be turned by a head 3% and may be heldin adjusted position by the check nut 3'! which engages the screw and bears against the plate 33. If it is desired to move the tongue part 23 further into the shuttle box, it is merely necessary to rotate the set screw 3| in a clockwise direction and then bind it in place by the check nut 3l. This will force the portion 23 against, its inherent resiliency into the position desired for fine adjustment of th'e surface of the back binder which engages the shuttle, to provide a greater area of Contact between the binder and shuttle thus increasing the checking elect of the binder. This adjustment may also be made to compensate for wear on surface 24. The adjustment is such that when the shuttle slot opening into the shuttle engagingside of the binder providing a longitudinally Vextending resilient tongue integral With'thefbody of the binder Witha surface in continuation of the swell,
